Molly spread the crayon-drawn invitation across the table like a battle map. "Party starts at two," she said. "Bouncy castle here, snack table here, and the presents pile up on this folding table by the hydrangeas." Bill squinted. "How many kids?" "Fourteen. Plus mothers." "Mothers are worse than dogs." "Mothers are worse than *anything*," Molly agreed. "But mothers watch each other. They don't watch the presents." Bill unwrapped a lollipop he'd stolen from a bank lobby. "So what am I, then?" "You're the entertainment. Clown suit's in the car." "Absolutely not." "Bill." "I have dignity. I did four years in Wandsworth with my dignity intact." "Nobody suspects a clown." "Everybody suspects a clown! That's the entire cultural understanding of clowns!" Molly tapped the hydrangeas. "You'll do balloon animals for eleven minutes. I'll load the wheelbarrow. We're gone before the cake." Bill chewed the lollipop stick, defeated. "What if a child asks me a question?" "Answer it wrong. Children love that." He stood, sighing, and collected the garish bundle of polyester from the sofa. "One condition," he said. "We leave the birthday boy's present. The big one, with the bike shape." Molly considered. "Fine," she said. "We're thieves, not monsters."
